ABSTRACT:
A grab-type tree harvester for processing trees comprises rotation means and a frame. The frame is connected to lifting means through the rotation means, in a manner such that the frame is adapted to rotate about a substantially vertical axis. The frame comprises grab means which are selectively moved by actuation means to an open or closed position, roller means for pulling a felled tree through said grab means, and at least one means for pruning the felled tree. The grab-type tree harvester is also provided with a jib that is pivoted on the frame and which, when a standing tree is being felled, is adapted to turn to a position substantially parallel to the tree being felled, by the aid of turning means. The jib is provided with means for gripping the standing tree, and also with sawing means for cross-cutting the standing tree.
